It is too early to determine whether the wounds are self-inflicted, but authorities suspect they were.

Crain is the sole suspect in the murders of his parents, 79-year-old Jim Crain and 76-year-old Eunice Crain.

Authorities described the scene as brutal and violent.

At a news conference today, Bayfield County Sheriff Paul Susienka said Saturday's 9-1-1 call for help came from Eunice Crain.

When deputies arrived, they found the couple deceased.

Authorities say their deaths were not caused by a firearm , but that it is too early to say what caused their deaths.

Their autopsies are expected to be completed later on today.

The Bayfield County Sheriff's Office is expected to file charges of first degree murder against Jimmy Crain in the death of his parents.

"That's the way we are treating this investigation. We're looking at first degree intentional homicide, but this is why it's important we have all the details and we are fully aware of what the injuries were and what motives there may be and continue to interview witnesses and gather our facts."

Under Wisconsin law, the maximum sentence for a first degree intentional homicide charge is life in prison

Once Crain is released, he will be taken into custody immediately and housed in the St Louis County Jail.

He will then have to go through the extradition process and be extradited to Bayfield County to face the murder charges.
